TrueDelta Reviews the Real Gas Mileage of the Chevrolet SS

Chevrolet SS Real Gas Mileage: Cons
Year	Comment
	My mention of a $1,300 gas guzzler tax foreshadowed this "why not." If you want a fuel-efficient car, you probably don't want a big, V8-powered sedan. But even compared to the Dodge Charger R/T the SS is a guzzler. This is partly because the very small number sold doesn't justify an upgrade to GM's latest engine and transmission technology, which includes variable valve timing, cylinder deactivation, and eight-speed automatic transmissions. These technologies enable the Charger R/T to earn EPA ratings of 16 mpg city, 25 mpg highway, while the SS can only manage 14/21 with a six-speed automatic or 15/21 with a six-speed manual (which skips from first to fourth under light throttle). In my real-world driving, the trip computer usually reported an average around 16 or 17 in the suburbs (20 if I drove with a very light foot) and MAYBE 24 on the highway. The trip computer in the Dodge reported averages that were usually higher by a couple MPG, but keep its engine in V4 mode (i.e. no lights to stop for) and the average can reach 30. see full Chevrolet SS review

2017	4dr Sedan 415-horsepower 6.2L V8 6-speed manual RWD	Wow, really, really bad. All the reviews you may have read about the fuel economy are dead on. You can optimistically get 24 on the freeway and low teens city. Then again you are NOT buying this car for fuel economy. see full Chevrolet SS review

2008	4dr SUV 300-horsepower 5.4L V8 6-speed automatic 4WD w/low range	Amazing fuel ecomomy for size....17.5 mpg overall, have hit over 20 mpg on 5 tanks, high is 22 mpg. 6-speed auto had 2 overdrives. see full Ford Expedition review

Ford Expedition Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2014	0	Seriously, what a pig. Not towing - mostly highway (over 400 miles worth) but some city driving as well - in 600 miles, we averaged 13.9 MPG. The car's computer appears reasonably accurate (as a rental, I do not know if it was really full when picked up but the second tank MPG was within 0.5 MPG of my calculation based on mileage). Yes, there were generally 6 passengers (4 adults, 2 kids) and the AC blowing (front and rear) to combate the Texas heat, but I was light with the thottle and it was quite flat. I am well aware no one will buy one of these based on gas mileage but this performance is just abysmal. Hopefully the next generation will improve. see full Ford Expedition review
2007	4dr SUV 300-horsepower 5.4L V8 6-speed automatic 4WD w/low range	It weights 3 tons, so fuel economy is not going to be great, but 13-14mpg in town and near 20mpg on the high way is achievable. see full Ford Expedition review
2005	4dr SUV 300-horsepower 5.4L V8 4-speed automatic RWD	13 in the city, 18 on the road, not bad but a diesel would be better see full Ford Expedition review
2004	4dr SUV 260-horsepower 5.4L V8 4-speed automatic 4WD w/low range	Vehicle is expensive to operate see full Ford Expedition review
2003	4dr SUV 232-horsepower 4.6L V8 4-speed automatic 4WD w/low range	10.7 mpg. Need to say more? see full Ford Expedition review
2000	4dr SUV 260-horsepower 5.4L V8 4-speed automatic RWD	The 5.4 L engine gulps fuel. Usually get 14 around town and best of 18 mph on highway if easy on the throttle. Probably all that can be expected of such a heavy vehicle with high wind resistance. see full Ford Expedition review
